"quit" in shell panics

[Sebastian Huber]

Hello,

the problem is that "bye" and "exit" are special cases in the shell to exit the 
loop.  There is also an "exit" command, which calls 
rtems_fatal_error_occurred().  This command does not execute due to the special 
case handling in the shell.  Only its alias "quit" can be reached.

I think we should remove the shell command "exit" and all its alias.  The 
"shutdown N" command can be used to invoke exit(N).

> There's a place where shell.c handles "bye" and "exit" specially, and I'm going to add "quit" in the same manner.  I don't see where that "quit" alias is added, though.  I don't have much time to go over the code right now, is there a way to get at the underlying command string so that aliases to exit are always handled cleanly without special code?
